For thin sections use Sikadur Aggregates, size dependant on layer
thickness. Keep water content at a
minimum.
The above mixes are for guidance only and based on the use of sharp, well
graded aggregates and dry sand. Trial mixes must be performed to establish the exact dosage rate required. For optimum results, always ensure
that the correct SikaLatex® : Water ratio is used. Depending on the application and performance required, Sika Latex® may be added to the clean mixing water within the range of 1:1 to 1:4. For all applications apart from
sprayed on renders, a bonding bridge should be brushed into the prepared
surface.

surface finish.
APPLICATION INSTRUCTIONS
SUBSTRATE QUALITY / PRE-TREATMENT
The substrate shall be thoroughly clean, rough, free
from dust, loose material, surface contamination. Delaminated, weak, damaged and deteriorated substrate

shall be removed by suitable means before application.
Rust, scale, dust and other loose and deleterious materials which reduces bond or contributes to corrosion
shall be removed.
MIXING
LOCAL RESTRICTIONS
Mix SikaLatex® with the correct amount of water to
produce a gauging solution.
Pour part of the gauging solution into a suitable mixing container. While stirring slowly, add the cementsand mix to the gauging solution and mix thoroughly
until a smooth, uniform and lump-free mix is achieved.
Within the mixing time add additional gauging solution to adjust to the desired consistency.
Note that as a result of specific local regulations the
declared data and recommended uses for this product
may vary from country to country. Consult the local
Product Data Sheet for the exact product data and
uses.
APPLICATION METHOD / TOOLS
For information and advice on the safe handling, storage and disposal of chemical products, users shall refer
to the most recent Safety Data Sheet (SDS) containing
physical, ecological, toxicological and other safety-related data.
Thoroughly pre-wet the prepared substrate a recommended 2 hours before application. Keep the surface
wet and do not allow to dry. Before application remove excess water example with a clean sponge. The
surface shall appear a dark matt appearance without
glistening and surface pores and pits shall not contain
water. Using a stiff clean brush work the mix vigorously onto the substrate, forming a thin layer filling all
unevenness, pits and pores.
Always apply following layer of mortar “wet on wet”
onto bonding bridge.
IMPORTANT CONSIDERATIONS
Never use pure SikaLatex® or SikaLatex®-water mix directly onto the substrate as bonding bridge, always add
cement and sand to the mix.
The standard rules of good practice for production and
placing of bonding bridge, repair and adhesive mortars must be observed when using SikaLatex®. Refer to
relevant standards.
Fresh applied mortar must be cured properly especially at high temperatures in order to prevent plastic
and drying shrinkage. Use Sika® Antisol® products as a
curing agent or apply wet hessian.
Higher dosages can be used depending on the mix
design, raw materials, climatic conditions and mortar
requirements.
Trial mixes must be performed to establish the exact
dosage rate required.
